This is related to closed issue #407.  The mime header property that is returning an exception is "Accept-Encoding". Need a way to ensure that valid Java Identifiers are added to jms headers or somehow eliminated. The current implementation just returns the given header name if no match is found in the CONVERSION_TABLE and set into the message header.
